Uninstall Jam Packs

I just installed the World Music Jam Pack onto my MacBook, but decided I had too little disk space afterwards and wanted to delete it for now.

I found files in 2 directories, a World Music Instruments and a Demo Songs directory.

I've deleted those 2 and it cleared up 9 gigs of space. Problem was when it installed it said it was going to need 12, so I'm wondering if there's something left over, or if the installer was incorrect about needing 12 gigs, or if I just wasn't paying good attention. I could have sworn there was some extra space kicking around before I installed it.
